Hello please provide your credit login (name).

Double credit withdrawals are refunded.  
Please try unlocking again, mainly the server should not charge credits again.  This can happen if unlock conditions change (e.g. ip address changes).  In your case there is a big time gap.

If there is a double withdrawal again, please let us know and we will refund the credits.
